Golf-course guide

1. A golf course guide, comprising: true to scale information maps, one for each individual hole for orientation about quirks and distances of the respective hole, each information map of the respective hole shown to scale indicating detailed golf course features of that respective hole which serve at least as an orientation aid for visual position determination, the information maps being orthophotos of the holes or a combination of orthophotos with overlaid vector data, information maps for holes of the golf course having the same par being configured to the same scale; and a single measurement aid with a plurality of distance scales that correspond to the scales of the information maps, the measurement aid being separate from the information maps and enabling distances of the holes to be determined upon overlaying of the measurement aid over the information maps, the measurement aid being a transparent plastic card or a transparent film made of a flexible material, the measurement aid including at least two sectors with centric distance ring sections that form different distance scales, each of the distance scales being associated with par 3, par 4 or par 5 and corresponding to the scales of the information maps provided for par 3, par 4 or par 5, respectively.

2. The golf course guide according to claim 1 , wherein the orthophotos provided for the information maps are distortion-free photographic images of the hole true to nature and true to scale.

3. The golf course guide according to claim 1 , wherein the measurement aid includes two sectors that form different distance scales corresponding to two different scales of the information maps for two of par 3, par 4 and par 5.

4. The golf course guide according to claim 1 , wherein the information map is a hybrid map wherein the orthophoto or orthophotos is or are combined or overlaid with vector data to add non-visible lines or individual points to the photos.

5. The golf course guide according to claim 1 , wherein the scales of the information maps are configured such that the distances of all of the holes of a golf course can be measured with just the one measurement aid.

6. The golf course guide according to claim 1 , wherein the transparent plastic card or film includes an illustration of the at least two sectors with centric distance ring sections, said distance ring sections forming the distance scale.

7. The golf course guide according to claim 6 , wherein the measurement aid includes three sectors that form three different distance scales corresponding to three different scales of the information maps for par 3, par 4 and par 5.

8. The golf course guide according to claim 1 , wherein the information maps have a markable surface in order to enable recordation of information thereon.

9. The golf course guide according to claim 1 , wherein the information maps are combined to form a booklet or a ring binder, the booklet or ring binder and the information maps being attached to one another.

10. The golf course guide according to claim 1 , wherein additional details such as terrain suitabilities, incline directions or other features not visible or only visible to a limited extent are included on the respective information map.

11. The golf course guide according to claim 1 , wherein the orthophotos are produced by aerial photos from a distance of between 50 and 1000 meters.

12. The golf course guide according to claim 11 , wherein the aerial photos for the production of the orthophotos are taken by means of a combination of different sensors.

13. The golf course guide according to claim 11 , wherein distortions occurring when taking aerial photos due to the photographic central projection and distortions due to differences in height of the terrain are corrected such that the orthophotos are produced by calculations using digitally stored terrain models.

14. The golf course guide according to claim 1 , wherein the orthophotos are provided of the holes at different seasons in order to take into account natural changes depending on season.

15. The golf course guide according to claim 1 , wherein the information maps are configured as a combination of orthophotos with overlaid vector data with additional graphic processing.

16. The golf course guide according to claim 1 , wherein at least one of the information maps includes indicia representing bunkers.

17. The golf course guide according to claim 1 , wherein at least one of the information maps includes indicia representing bushes.

18. The golf course guide according to claim 1 , wherein each of the at least two sectors extends from a respective zero point, and the at least two sectors do not overlap one another.

19. The golf course guide according to claim 1 , wherein the at least two sectors includes only two sectors, the two sectors being in mirror image to one another such that positioning the transparent plastic card or transparent film with one planar surface facing upward enables use of one of the two sectors and positioning the transparent plastic card or transparent film with the other planar surface facing upward enables use of the other of the two sectors.

20. The golf course guide according to claim 1 , wherein the information maps include only one information map for each hole of the golf course.
